my b16a in my crx with my pr3 ecu is idling high. usually idles at 1k when cold and 700ish when at operating temp. now its idling at 2k and 1800 or so.

background info. removed my charcoal canister. it wasnt hooked to anythign anyway. just sitting there on the firewall other than the large hose underneath that connected to the bottom of the canister and runs into the fenderwell.

also, i reset my ecu by unplugging the negative terminal for a few hours. when i fired if back up... high idle.

 

re-connec the hose and see what happens,

or plug up the hole that the tube was connected to..

sounds like it vents to the throttle body past the plate..

So that tube would be the one that opens up and lets in the gas fumes from the charcoal canister..

 

thats the part thats got me boggled. nothign from the canister was ever connected to the TB when it was runnign correctly. im re-resetting my ecu now and im gogin to see what happens.

weird.

 

did you unplug your map sensor?because i had the same thing happen to me and it was the map sensor also check all of your vaccum lines to.good luck
